When they grow molars to chew with. Give them whole carrots to snack on.

To expand and agree: turnips, beets, hard whole grains, if their baby teeth aren't visibly worn by the time they fall out, it wasn't hard enough.

Jaw and face bone grows by stimulation. It's not just a dental thing - it's sleep apnea, sinus infections, facial structure, voice timbre, and attractiveness.

If it's enough, they won't even need their wisdom teeth pulled - having your wisdom teeth pulled is substantially a standard american diet issue, not a human genetic issue.

Thanks, and 100% agree. We have never had to pull a wisdom tooth either and carrots were always the go-to roadtrip snack growing up.

It's funny because I mildly disagree with your core premise (orthodontics are unnecessary), they should just be necessary as a disability accommodation, essentially. If we had 10-30% of the population in wheelchairs because we didn't let kids walk I would find the wheelchair industry odious as well.

Right, most of the orthodontics websites say 70% of people need them. I understand wanting to justify a total market size but if people actually believe that, it's getting out of hand.

I've had carrots (and fruit and hard snscks) since I don't remember when.

My teeth have been crooked since forever. So?
